[Decision-Making Behaviour in Physician-Rating Portals: Results of a Vignette Study in the New Federal States of Germany]. / Das Entscheidungsverhalten in Arztbewertungsportalen. Ergebnisse einer Vignettenstudie in den neuen Bundesländern.

BACKGROUND: The extent to which relevant information is taken into consideration in the decision process for or against the choice of certain physicians when searching for physicians via physician-rating portals is largely unknown. In particular, the question of whether longer travel distances to a doctor's office are accepted in favour of a good rating is investigated in this study. METHODS: In a vignette study, 192 respondents from new German states were shown ten hits each from a fictitious search for a primary care physician. A total of 1881 choice probabilities were evaluated with cluster-corrected regressions. RESULTS: A good rating and a short distance to the doctor's office were the most important determinants of a positive probability of choice. Longer distances were not accepted in favour of a good rating. Arabic-sounding names strongly reduced the probability of choice, although the respondents only assigned subordinate importance to the doctors' names as a basis for decision-making. CONCLUSION: The area served by physicians in private practice does not increase if they receive good grades on rating portals. Service quality is important, but not the most important factor in the rating score.
